To all ibbmiit oici/ concern:

'Be it known that 1 lDOiislnf- MCCALL .Vlriiiria a subject of Great Britain,'1'csiding at Detroit, Vin .tlie'county'of Wa ne and StateV of- Michigan, have-invente certain new anduseful Improvements in Automabilc Constructions, of which the following l This` invention relates to automobil and has 'for itsvobjecta special form of c assis "frame construction combinedl with a 'Worinor 4siiral gear drive which is under-slungv on t e rear axle. This perixiitsof. a,v deeper drop frame and secures a chassis frame 'the group 'thancan bc otherwise. attained with the ordinary chassis frame andra'xle land A further featureof the construction is an improved bracin .effect secured at the point where the bcn is made intliechass'is frame by means of a cross running tubegin place o'f theusual channel constructulvn.i These and other features will be described in detail in a description following the erinmeration of the figures. e

Fig. l is a. plan view of the chassis frange `and the drive. Q j Fig. 2 is a side elevation showing the samc parts some of them in dotted line.

Fig. 3 is a large longitudinal section of the ioar part of the same on the line 3--3 of Fig.. l.

The automobile construction here shown is intended to be one belonging to the high 'grade class which combines notonly strength,V but quality features, no't found in thc ordinary runA of cars. The chassis f rainc is. made up of pressed steel heavy section channel bars such as shown in the drawing. These channel bars are 'pressed a very m'uchdecper rop than isv customary with the ordinary chassis frame construction. ln fact the loivcr side of the channel bal' clears thc ground hy only 13 inches and the running boni-d is only l2 inches above the ground. The floor of the car is only about 20 inches above the ground. This makes n vcryr low liunir car which ismost desirablc in providing case in climbing in and out of the car and also in havinithe weight .of the car hung low so that c car will keep the road better at high speed.

These low side bars of the chassis frame o rton of which isncarer to the` drop in the frameslu'n torque tube or, propeller shaft tubo; this is designated a and -it will be seen that therear axle housing is provided with an un'dersliini;r integral gear or worm housingv .ariclinarle 'possible by. reason of the under? c to 'which the Vrear end of .the propeller shaft tube is' secured. The ordinary beveled gear dri-vemeets the rear uxleliousing at the center of thefront and the ordinary worm'geal-- drive meets thc rear axle housabov'd'tlie* same. By .undersl inging theV propeller-.shaft and iisin a worm and worm ear, the -torque tu il eV transmission, an the e e, 'can be lung' atasvery much' lower llgiiiil with re- ,sllicct to the axle and wheels tlian has herc- 4tofoi'e been.-posshle. .Hence 'it very much deeper' drop frame -can be einployed. It vigil howe'vit' rear of the c assis frame 'the ordinary distance above the axle do as to "ve the rear' 'axle .the usual free spacein w `cli to move i response to the irregularities linthe rond.

It will-be seen that with-the arrangementothe parts described .that this low chassis frame construction is secured without having to kick up the cross'e channels y and I; inorderto clear tho drive( Obviously if these "cross channels had to .be kicked upiinorder to clear the to u'etiib`e, then thel lower chassis frame woul bof no adva tage nsthe Hoor of the ca rfcoilld not very well be lowered on aceoiniti'of` .kicking up' the cross channels.

In order to more thoroughly strengthen the chassis frame -where the unusually dcep drop occurs, l einplo in place of the -usual 'cross channel, an. 'en ilanged-tiibe k which obviously has more strength inthe direction of forces than the cross channel. This makes the frame an unusuall stron one.

Itis inadvisable of course in the c aims to specify the' arnountof drop iii measurement of inches. vIt will be apparent, however, that the drop in the chassis frame is quite alittle below the center of the rear axle and that this forms a simple criterion for speci fying the new and novel arrangement; for an ordinary chassis frame and axle con` ie universal joint, 'V
